Ward: Sacrifice a Legendary permanent.
Whenever a creature deals combat damage to
an opponent, that creature's controller creates
two clue tokens.
Whenever Lena Atherton deals combat
damage, you may sacrifice any number of clues.
If you do, deal X damage to each opponent and
gain X life where X is twice the number of
clues sacrificed this way.
